Additional Postoperative Radiotherapy Prolonged the Survival of Patients with I-IIA Small Cell Lung Cancer: Analysis of the SEER Database

Figure 3

An example for utilization of proposed nomogram. A random patient was chosen from the population in this present study. She was a 70-year-old female with T1N0M0 SCLC who underwent lobectomy and chemotherapy. After PORT, the probability of her 10-year survival was 54.7% (0.95 CI [42.3%, 65.5%]). The violin plots exhibited the density distribution of the numeric variables age and total points. The box plots reflected the distribution of category variables. The red points on the “Points” line corresponded to score for each covariate. Total points equaled to the sum of scores for all covariates, which was 420 in our nomogram. The 3/5/10-year OS probability was predicted based on it.
